---1Means within a column followed by the same letter are not significantly different (P<0.05, DMRT). 2Averages are from four years of trial work, two CA and two FL trials per year.
3Averages are from three years of trial work, two CA trials in 2000, one CA trial each in 2001 and 2002, and two FL trials in 2000 and 2001. 4 Primary soilborne pests / pathogens in the Ca strawberry trials were “root-nibbling” fungal pathogens, including Rhizoctonia solani, Pythium
spp., and Cylindrocarponspp.
5 Primary soilborne pests in the Fl strawberry trials were the sting nematode (Belonolaimus longicaudatus) and yellow nutsedge (Cyperus
esculentus).
6 Primary soilborne pests / pathogens in the Ca tomato trials were the soilborne fungal pathogens Verticillium dahliaeand Fusarium oxysporum.
Incidence of both pathogens was low due to repeated historical use of mb / pic.
7 Primary soilborne pests / pathogens in the Fl tomato trials were the root-knot nematode (Meloidogynespp.), Verticillium dahliae, and yellow
